AUTOMATIC BRAKE APPARATUS FOR TORPEDOES.

SPECIPICATIONforming part of Letters Patent No. 361,525. dated April 19,1887.

Application filed February 4,1887. Serial No. 126,544. (No model.)

To aZZ whom, it may concern:

Be it known that], EMIL KASELOWSKY, a subject of the King of Prussia,residing at Berlin, in the Kingdom of Prussia, German Empire, haveinvented new and useful Improvements in Automatic Brake-ReleasingMechanism for Torpedoes, of which the following is a full, clear,andexact description.

In projecting torpedoes by means of compressed air or gas, or by theexpansive force of combustible gases, it is very desirable that thebrake mechanism be released simultaneously with or slightly before theapplication of the projecting force to the torpedo, in order to avoidthe possibility of the projecting agent being admitted to thetorpedo-tube while the brake is applied.

To this end my invention consists in a brakereleasing mechanismoperating automatically by the motive agent that effects the projectionof the torpedo, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a partofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of a torpedo-case having an ordinary brake andmyimproved brakereleasing mechanism applied thereto, thebrake beingshown as applied to the torpedo. Fig. 2 is a plan view of the same. Fig.2 is a section of the torpedo-tube on the linew or of Fig. 2, the brakebeing omitted. Fig. 3 is an enlarged longitudinal sectional elevation ofthe brake-releasing mechanism. Fig. 4is a crossscction of a torpedo caseor tube provided with the ordinary band-brake. Fig. 4 is a detail View,and Figs. 5 and 6 illustrate the ordinary block-brake for torpedo-tubes.

A small cylinder, a, is mounted on the torpedo case or tube A,preferably near the rear end thereof, and in the cylinder a is fitted apiston, b, the piston-rod cof which is extended forward longitudinallyof the tube A and connected with the arm or lever d of the brake, whichis located at the forward end of the torpedo-tube, as is usual. Theother end of the brake-lever d is connected with theeccentrically-operating stud or arm 6, extending into the torpedo-tube Aand secured to one end of the brake-band f. When the block -brake shownin Figs. 5 and 6 is used, the rod 0 is connected to the brake-lever m,that is connected to one end of the shaft that operates brakeblock n.

Around the piston-rod 0, within the cylinder a, is coiled a strongspiral spring, is, its one end normally acting to press the pistonagainst the rear end of the cylinder a, and the other end of the spring7a bearing against the cover or head i of said cylinder at. Fulcrumed onthe side of the torpedo-tube A is a hand-lever, g, the head or upper endof which is'formed with ratchet-teethj. In addition to being fulcrumedon the torpedotube A,the hand-lever g is also pivotally secured to' therod 0 at a point, as at r, on the said lever between its toothed headand its fulcrum. On the top of the cylinder at is suitably mounted aspring-pressed pawl or dog, h, that engages the toothed upper end, j, ofthe hand-leverg. Communication is established between the interior ofthe cylinder to and the interior of the torpedo-tube A by means of theconnecting way or passage 1.

In operation, gas or air, being admitted to the torpedo tube or case inthe usual manner to discharge the torpedo, will enter the cylinder (1through thepassagel in sufficient quantity to force forward the pistonb, and with it the piston-rod c. As the rod 0 moves forward it swings orthrows the brake-lever d, which turns the eccentric brake-arm or stud eand releases the band-brake f from the torpedo; or, when the block-brakeis employed, the throwing of the bral e-lever by the rod 0 acts torelease the hold of the brake-block n on the torpedo. As the rod 0 movesforward, as described, in response to the movemennt of the piston b, itcarries forward the toothed upper end, j, of the hand-lever g, and thereturn of the said lever, and of course the rod 0, to the normalposition is prevented by the springpawl h engaging the teeth j on saidlever 9. When the brake is again to be'applied, the spring pawl isdisengaged from the toothed end j of the lever g by the hand-lever 0,and the spring will force the piston backward, and with it the rod 0,and again apply the brake and hold the piston in its normal positionuntil the next charge of compressed air or other agent is admitted tothe torpedo-tube. 1

While it is preferred to locate the cylinder a near the rear of thetorpedo-tube A, it may be located at a more forward point on the sameand the passage Z extended to effect communication with the interior ofthe torpedo-tube. The advantages of placing the cylinder near the rearof the torpedo-tube will, however, be apparent.

1t is evidentthe details of the invention may be varied withoutdeparting from the spirit of my invention. For instance, instead offorcing the rod 0 forward to release the brake, it is very evident thatthe reverse movement of the rod. 0 may readily be made to effect therelease of the brake.

With my automatic brake mechanism,abovc described, the danger ofadmitting the motive ,agent while the brake is applied is entirelyobviated and accidents arising from this cause made impossible.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In combination with a torpedo-tube and itsbrake, a cylinder in communication with the interior of the said tubeand a piston in said cylinder, the piston-rod of which is connected withthe brake, substantially as described.

2. In combination with a torpedo-tube and its brake, a cylinder mountedon and in communication with the torpedo-tube,and aspringpressed pistonwithin said cylinder, the pistonrod of said piston being connected withthe brake, substantiallyas described.

3. In combination with a torpedo-tube and its brake, a cylinder incommunication with the interior of the torpedo-tube, a piston in saidcylinder, the rod of the piston being connected with the brake, and atoothed lever pivoted to the brake-releasin g rod and engaged by aspring pawl or dog, substantially as de- EMIL KASELO\VSKY.
